Japanese innovation aims to ease elderly caregiving with automated, full-body bathing technology
A once-futuristic concept has moved closer to everyday reality as Japan prepares to commercialize a machine designed to transform how people bathe, especially in aging societies where caregiving demands continue to rise.
From Expo Showcase To Commercial Product
The so-called human washing machine, developed by Osaka-based bath and shower equipment manufacturer Science Co., will officially go on sale in 2026. The device gained widespread attention after being showcased at the World Expo in Osaka, which concluded in October and attracted about 27 million visitors. According to Kyodo News Agency, more than 1,300 people tested the machine during the event, signaling strong public interest.
Designed To Reduce Caregiving Burden
Science Co. chairman Yasuaki Aoyama said the machine is intended to reduce the physical burden of bathing on both users and caregivers. This is especially relevant for elderly individuals and care facilities, where bathing assistance is often one of the most physically demanding tasks. Shipments to caregiving facilities are scheduled to begin in March 2026, followed by sales to the general public by the end of the year.
How The Machine Works
The main consumer model resembles a raised rectangular bathtub with a side-entry door and a built-in seat. Users sit comfortably while the machine fills with water. It uses fine-bubble technology that creates extremely small bubbles capable of reaching skin crevices, enabling full-body cleansing without shampoo, soap, or scrubbing. Each bathing session takes approximately 10 minutes.
Pricing And Availability
The standard model will be priced at 1.45 million yen, or about S$12,000, making it more accessible to care facilities and private homes. According to the company, requests for commercialization have come from both domestic and international markets, reflecting growing global interest in assisted living technologies.
A Premium Capsule Version
In addition to the standard unit, Science Co. also unveiled a more advanced and significantly more expensive capsule-style human washing machine. Measuring 2.3 meters in length, this model includes a fine mist shower, automated drying, and sensors that monitor the user’s health during the bathing process. The entire cycle takes about 15 minutes and is enhanced with calming visuals and music.
Early Adoption In Hospitality
This premium version, estimated to cost around 60 million yen or approximately S$493,000, has already been adopted by Dotonbori Crystal Hotel III in Osaka. The hotel offers the machine as part of its day spa experience, allowing groups of up to four people to book a private 90-minute session priced at 18,000 yen, or about S$150, although guests must take turns using the device.
Japan’s human washing machine highlights how technology is being adapted to address demographic aging and caregiving challenges. As societies in Indonesia, Singapore, and across Asia face similar pressures from aging populations, innovations like this may influence future healthcare, hospitality, and assisted living solutions across the region.
